What do long-legged bees fear most?

Spider. Long-legged bees will be eaten by spiders as long as they are accidentally stopped by cobwebs, and there is no chance of survival at all, so long-legged bees are most afraid of spiders. Long-legged bees, gentle in character, will not take the initiative to attack people, and often nest under trees or buildings. Except in winter, adults can be seen, living in flat land or low altitude areas.
